Before DFW was cars and concrete, it was prairie 🌾 This is a cool as heck 200-acre remnant called Tandy Hills that includes rocky limestone and marl soils, has over 1,500 documented plant species including several rare and endemic species. This is in Forth Worth, part of the Eastern Cross Timbers which lies directly west of the Blackland Prairie ecosystem where Dallas is. DFW, this is in your backyard!! Take your kids, your friends, go walk it, and help protect the last pieces of this ecosystem.
